2019-06-11

Foam glass was first invented by Corning Incorporated of Pittsburgh, USA. It is made of cullet, foaming agent, modified additive and foaming accelerator. After fine pulverization and uniform mixing, it is then melted at high temperature, foamed and annealed. Inorganic non-metallic glass material. It consists of a large number of uniform bubble structures with a diameter of 1 to 2 mm. Among them, the sound absorbing foam glass is more than 50% open cell bubbles, and the heat insulating foam glass is more than 75% closed cell air bubbles, which can be adjusted according to the requirements of use, through the change of production technical parameters. Because this new material has the functions of moisture proof, fireproof and anti-corrosion, and the glass material has the advantages of long-term use performance, it is in a harsh environment such as heat insulation, deep cooling, underground, open air, flammable, damp and chemical attack. It is favored by users. It is widely used in wall insulation, petroleum, chemical industry, machine room noise reduction, highway sound absorption barrier, electric power, military products, etc., and is called green environmental protection insulation material by users.
